Gluten can be a hidden ingredient in many things other than food…glue on envelopes (remember the episode of Seinfeld in which George’s fiance dies from licking wedding invitations?) – laundry detergents – soaps and shampoos – toothpaste and mouthwash – Rx drugs and health supplements (vitamin pills, etc.) – lip stick and lip balm Sunscreen as well as other cosmetics, lotions and creams.
If your diet is gluten-free, but you still have symptoms related to ingesting gluten, you may need to check your medicine cabinet and cosmetics bag. The link below is for gluten-free lipstick.
